vsi_unlink_batch()
deletes a list of files passed in a character vector.
All files should belong to the same file system handler.
This is implemented efficiently for /vsis3/ and /vsigs/ (provided for
/vsigs/ that OAuth2 authentication is used).
This function is a wrapper for VSIUnlinkBatch()
in the GDAL Common
Portability Library.
Value
Invisibly, a logical vector of length(filenames)
with values
depending on the success of deletion of the corresponding file.
NULL
might be returned in case of a more general error (for example,
files belonging to different file system handlers).
Examples
# for illustration only
# this would normally be used with GDAL virtual file systems
elev_file <- system.file("extdata/storml_elev.tif", package="gdalraster")
tcc_file <- system.file("extdata/storml_tcc.tif", package="gdalraster")
tmp_elev <- paste0(tempdir(), "/", "tmp_elev.tif")
file.copy(elev_file, tmp_elev)
#> [1] TRUE
tmp_tcc <- paste0(tempdir(), "/", "tmp_tcc.tif")
file.copy(tcc_file, tmp_tcc)
#> [1] TRUE
result <- vsi_unlink_batch(c(tmp_elev, tmp_tcc))
print(result)
#> [1] TRUE TRUE
